Question about 2000 Buick Century
Find the egr valve on the intake. Look up on the internet what it looks like because it is difficult to describe. There will be one vacuum hose attached to it. Start the car and let it warm up. when it starts to hesitate remove the hose. If the engine holds idle, you need to replace the egr valve. The egr (EXHAUST GAS RECIRCULATION) valve allows the engine to re burn the exhaust gas when the engine is cold to clean up the emissions at the tail pipe. They tend to get stuck in one position from carbon build up and need replacement.
